(a) As zero value for n is not possible, this set of quantum numbers is not possible.

(b) This set of quantum numbers is possible.

(c) As

l = 1

is not possible for

n = 1

, this set of quantum numbers is not possible. For a given value of n, l can have values of

0, 1, 2 ... n - 1

only.

(d) This set of quantum numbers is possible.

(e) As

l = 3

is not possible for

n = 3

, this set of quantum numbers is not possible. For a given value of n, l can have values of

0, 1, 2 ... n - 1

only.

(f)This set of quantum numbers is possible.
